TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 527,544, dated October16, 1894.

Application filed March 5, 1894. S ial No. 502,370. (No model) To allwhom it may concern.-

Be it known that I, ZALMON G. SHOLES, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Type-Writers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My invention relates particularly to platen carriages of type writers,to the ways upon which said carriages reciprocate, and to mechanism forguiding the inking ribbon.

The object of the invention is to produce a platen carriage, ways forsaid carriage, and guides for the inking ribbon, all of which may bereadily removed from and replaced upon the machine, to the end thataccess may be readily had to the parts of the machine located beneaththe carriage.

In the accompanying drawings: Figure 1 is a plan of a portion of a typeWriter embodying my invention, Fig. 2 is a front elevation. Fig. 3 is avertical section in line a-b of Fig. 1. Fig. 4. is a vertical section inline ac of Fig. l.

' A is the upper portion of the frame of the machine. This may be of anywell known form.

A is the central opening through which the well known type bars rise toreach the platen.

A ,A are openings in said frame through which the inking ribbon, Apasses.

A A are parallel dove-tail grooves extending from the front of the upperportion 1 of the frame, A, rear ward through the latter almost to therear of said frame. B, B, are dove tail bars accurately fitted into saidgrooves, but loosely enough to permit longitudinal reciprocationtherein. At any convenient point in each of said bars a binding screw,B, extends through'said bar and is adapted to be pressed against thebottom of the groove, A in which said bar is located.

By means of said screws, said bars may be immovably bound in saidgrooves.

O O are parallel rails each extending from one of the bars,.B, to theother and having their ends secured to said bars by any suitable means.For this purpose,I prefer to apply a short cross piece, 0, at each endof said rail between the latter and the adjacent bar, and attach saidcross pieces to said bar by means of screws, 0.

D is the platen carriage. This is arranged to reciprocate upon therails, O, in any suitable manner. The drawings show the opposing facesof said rails provided with tongues, 0 extending into grooves, d, in theedges of the carriage.

I deem it unnecessary to illustrate and describe the manner of applyingthe platen to the carriage, for this is well understood by thosefamiliar with this art.

E E are ribbon guides extending from one rail, 0, to the other at eachside of the center of the opening, A. Said guides extend beneath thecarriage, D, and are attached rigidly to the said rails, C. To providefor the release of the ribbon when the carriage rails are removed, Ihave provided for temporarily forming a gap at the middle of each ofsaid supports. To this end each of said supports consists of two rods,E, approaching each other from the opposite side rails and a loosesleeve, E surrounding said rods and adapted to be moved longitudinallyupon said rods to uncover the gap between the adjacent ends of saidrods. When the carriage rails are to be removed, the sleeves, E

are slipped toward one of the rails untilsaid gap is exposed, and thenthe inking ribbon is moved downward through said gaps. Then said guidesand said rails are free to be lifted away Iv claim as my invention- 1.In a typewriter, the combination with the frame, A, of bars, B,detachably secured to said frame, rails, G, secured to said bars, and aplaten carriage, D, and separable ribbon-supports applied to said rails,substantially as described.

2. In a type-writer, the combination with in presence of two Witnesses,this 26th day of February, in the year 1894- ZALMON G. SHOLES.
